T0 all whom t may concern.' f

Be it known that PAUL MAUsER, deceased, formerly residing' at Oberndorf-.ondhe Neckar, Germany, and formerly a subject of theling' of lurttemberg, invented certain new and useful lmprovements in Firearms, of which the following is a specification.

rlhe present invention relates to a breech construction for lire-arms with the handle attached to the breech bolt, and a recess in the breech casing into which recess the said handle enters on the breech being opened.

rllhe present invention has as its object to provide a simple and reliably acting construction by means of which on the one hand the recess in the breech casing is closed, when the breech is closed, while on the other hand the facility of mowing the handle in the recess of the casing' for opening and closing the breech is insured.

In order to attain this object a plate is provided, according' to the present invention, longitudinally displaceable in the ing or in the lid of the casing, which plate, on the breech being opened, is pushed back by a member, longitudinally kdisplaced by such opening (for example by the breech bolt), so that the recess inthe casing is cleared for the entrance of the handle, while, on the breech being closed, the said plate is advanced into closing position.

The invention has been exemplified in the accompanying` drawing. Figures l and 2 are elevations, partly in vertical longitudinal section,l showing the respective parts in closed and open position, respectively. Fig. 3 is a view of the lid, seen from below, with the closing' plate in closed position. Fig. 4 is a diagram showing the coaction of the breech bolt with the closing plate, on the breech being` closed. Fig. 5 is an elevation corresponding to Fig. l, Fig. 6 a cross section on the line VI-VI in Fig. 5.

`To the breech bolt 7c is attached at the side a handle (Z, which serves for opening' and closing the breech by hand. In order to allow of this handle being freely movable in opening and closing' the breech, a recess is provided in the breech casing' It, which recess is closed by means of a plate a when the breech is closed. This plate c is provided at its forward end with a projection a1 which, in the eXempliication shown in the drawing,y has ,been formedwby the forward fend ofthe pla-te having been bent over. The; platevr c is ylong ,'itu"dinally d-isplaceable, with ianges formed at its upper edge in a dovetail groove in `the-lid of the breech casing (Fig. 6).

On the breech being closed a nose /cl at the rear end of the breech bolt 7c engage-s behind a projection al of the closing plate, so that the latter is advanced,.together with the breech bolt, into closing position (Figs. l and On the breech being' opened, the rear edge of the handle cl engages in front of the front end of the closing plate a and pushes the latter so far back as is necessary for allowing of a Vfree movability of the handle in the recess in the casing' (Fig. 2).

For facilitating its being fitted into the casing the closing plate is made, according to the present invention, in form of a doubled spring' of an angle section, the two legs of which may be compressed so far that their guide flanges can enter into the groove in the lid and, thereafter, by their elasticity, safeguard the closing plate against any unintended displacement in the guide groove.

Claims:

1. A firearm comprising a breech casing, a breech piece therein, a handle for operating said breech piece, a slot in said casing in which said handle is adapted to move, and a plate independent of said handle and breech piece and adapted to be operated by two shoulders on said breech piece to open and close said slot, said plate being movable parallel to the direction of motion of the breech piece and having a lost motion with respect to said shoulders.

2. A firearm comprising a breech casing, a breech piece therein, a handle for operating said breech piece, a slot in said casing in which said handle is adapted to move, and a plate independent of said handle and breech piece and adapted to be operated by a movable part of the breech mechanism to open and close said slot, said plate being in the form of a spring adapted to bear against the casing -to retard movement of the plate.

3. A firearm comprising a breech casing, a breech piece therein, a handle for operating said breech piece, a slot in said casing in which said handle is adapted to move, and a plate independent of said handle and breech piece and adapted to be operated by a movable part of the breech mechanism to open and close said slot, said plate being in the form of a spring of angle material adapted to bear against the casing to retard movement of the plate.

4. A firearm comprising a breech casing, a breech piece therein, a handle for operating said breech piece, a slot in said casing n which said handle is adapted to move, and a plate independent of said handle and breech piece and adapted to be Operated by two shoulders on saidbreech piece to open and close said slot, said plate being movable parallel to the direction of motion of the breech piece and having a lost motion with respect to lsaid shoulders, said plate havingtwo shoulders both near one end thereof, adapted to coperate with the shoulders on said breech piece.

In witness whereof, I have hereunto signed my name in the presence of two subscribinggf` witnesses.
